Very sad news, this is more than just another celebrity death to me. 
I started showing my wife his clips quite a while ago. I also went to one of his events with my wife some years ago. 
She is upset right now and cried a bit.
At that event he had Giuliani and Glen Beck as well. 
I think Charlie was really influential to the point someone got threatened. Probably a leftist, but politics is a dirty game.
